distance between prallel plate capacitor is increased what happens to the charges on plates, potential difference across plates, energy stored in the capacitor |
|
Answer» The FORMULA for the capacitance of a parallel plate capacitor is C=ϵAx, where ϵ is the permittivity of the medium between the plates, A is the OVERLAPPING area of the two plates and x is the uniform separation between the plates. Capacitance, intuitively, is the ability of a pair of conductors separated by a dielectric to store ELECTROSTATIC energy - or in other words, how much charge the conductors can store at a given VOLTAGE level. It is analogous to the CAPACITY of a bucket being how much water it can hold. Q=CV Assuming that the capacitor is connected across a constant voltage source keeping V constant, increasing the distance between the parallel plates will decrease C at a constant V, an increase in C will decrease the charge Q that the conductors can hold. |

if a police car running after a thief's car with the speed 126 km/hr if a bullet is fired from the police car with the speed of 200m/s .If the speed of police car is 36 km/hr.if the initial distance between police car and thieves car is 200 m .Find out whether bullet will hit the thief car |
|
Answer» speed of thief's car = 126km/hr = 35m/s speed of police car = 36km/hr = 10m/s speed of bullet = 200m/s initial separation between thief's car and police car = 200m As the bullet was fired from a police car that was already moving with a speed of 10m/s, the speed of the bullet relative to GROUND = 200 + 10 = 210m/s Now, the relative speed of the bullet as seen by a thief in his car = 210 - 35 = 175m/s It means that if you consider the thief's car as a STATIONARY object, then the bullet approaches the thief's car with a speed of 175 m/s So, the time in which the bullet reaches the thief's car = 200/175 =1.14 seconds Thus, the bullet will definitely HIT the Thief's car. Hope it helps!! |

explain how is it impossible from an object to move with constant speed but with uniform acceleration |
|
Answer» An object moving in a circle is accelerating. Accelerating OBJECTS are objects which are CHANGING their VELOCITY - either the speed (i.e., MAGNITUDE of the velocity vector) or the direction. An object undergoing UNIFORM circular motion is moving with a constant speed. |

Two electric bulbs are rated as220V-100W and 220V-60W.which these has greater resistance and why? |
|
Answer» For FIRST bulb Potential difference = 220 V Power supplied = 100 W We know that P = V²/R So, 100 = 220 * 220 / R R = 220*220/100 = 484 ohm For second bulb Potential difference = 220 V Power supplied = 60 W We know that P = V²/R R = 220*220/60 R = 806.6667 ohms. Hence, from calculation the second bulb has more resistance. More is the power, LESS is the resistance and conversely less is the power, more is the resistance. This is the reason. Hope this helps you. |
